Dr Arnoud van Vliet is a Senior Lecturer in Microbiology at the School of Veterinary Medicine of the University of Surrey. His research focuses on zoonotic bacterial pathogens, with an emphasis on those transmitted through the food chain, such as Campylobacter. Despite strong biosecurity measures, Campylobacter is able to persist in the agricultural environment and colonize poultry and farm animals, and is subsequently transmitted via the food chain. While easy to kill in laboratory conditions, Campylobacter is a resilient pathogen that has been able to adapt to changes in agricultural practice and food preparation. His research looks at the role of biofilms in the transmission and persistence of Campylobacter, and investigates the role of genetic diversity between isolates, with the ultimate aim of identifying targets for detection/treatment/vaccination. Other areas of interest are in the use of genome sequencing for a better understanding of virulence mechanisms, immune escape, phage defence and antimicrobial resistance.
